一、概述随机振动试验,对其实地模拟大多数试件的振动环境是必不可少的,这一点越来越为大家所接受。因为,飞机、火箭发动机,气动紊流等产生的扳动基本上是随机的而不是正弦的.这种振动,激振频域很宽并具有一个连续的能谱。虽然大家认识到了做随机振动试验的必要性,但由于设备的限制以及随机扳动试验技术和数据处理等远比正弦扳动试验复 First, an overview Random vibration test, on the ground to simulate the vibration of most specimens is essential, it is more and more accepted by everyone. Because the plane, rocket engine, aerodynamic turbulence generated flip is essentially random rather than sinusoidal, this vibration, the excitation frequency domain is very wide and has a continuous spectrum. Although we recognize the need to do random vibration test, but due to equipment limitations and random pull test technology and data processing than the sine pull test complex
